Patented July 28, 1942 ARTICLE OF BEDDING George W. Gartz, Springfield,N. J., assignor to Burton-Dixie Corporation, Chicago, Ill., acorporation of Delaware Application December 14, 1940, Serial No.370,150

4 Claims.

The present invention pertains to pillows, cushions, or other articles,which may be more or less aptly characterized as non-allergenic, inthat, since some persons are detrimentally affected by breathing theallergen, pith or dust, incident to the use of feathers, down or thelike, the novel pillow, cushion, or other articles constituting thesubject-matter of this invention are so constructed as to preclude theemanation of such fine material from the pillow or the like while in useand without modifying the resilient and elastic properties of the pillowupon which the comfort of the user is dependent.

An important object of the invention is, therefore, to provide a pillowor the like made in such a way that the powder produced by the fillingof the pillow while in service, probably due to attrition or rubbing ofthe feathers or particles of down on one another, and possibly also byreason of the disintegration of the feathers or down based upon theirdeterioration, cannot escape through the pillow cover or casing, and,accordingly, the fine dust is precluded from reaching and detrimentallyor injuriously acting upon the user of the pillow.

A present improved embodiment of the invention is illustrated in detailin the accompanying drawing forming a part of this specification andthroughout the views of which, for simplicity, like parts have beensupplied with the same reference numerals.

In this drawing:

Figures 1, 2 and 3 show steps in the method of making the novel pillow;

Figures 4 and 5 are enlarged cross-sections on lines 4-4 and 5-5,respectively, on Figure 3; and

Figure 6 is a longitudinal section through the completed pillow.

Referring to these several views, it will be noted than on top of anouter, fiat sheet of textile-fabric H is laid a thin layer ofcottonbatting I2 of the same size as sheet II and gluesized throughoutits top and bottom surfaces, such part l2 being about inch thick witheach of its opposite sized-faces continuous or imperforate.

Then on top of such stratum I2 is deposited another inner textile-fabricsheet 13 of the same size, whereupon the three strata are stitchedtogether along one margin at [4.

Two of such triplicate members of equal size having been made in thismanner, they are superimposed on one another in register with with oneanother, as shown in Figure 2, except that for clarity one corner of onesuch member is depicted as folded back to disclose the other underlyingthreefold member.

Thereupon, the two treble members, that is the six strata, are stitchedtogether along the remaining three margins l5, It and I1 and then suchstitched article with one end open or unstitched is reversed or turnedinside out as presented in Figures 3, 4 and 5.

Such casing or envelop is then filled through its open end withfeathers, down, kapok, or other resilient and elastic material l8, afterwhich the two upper and lower members are stitched together along a lineI9 (Figure 6) at the mouth of the sack or casing thereby securely andeffectively closing its previously open end and providing a completelyenclosed filling surrounded by the cotton-batting layer and thetextile-fabric sheets.

A pillow has to have a certain measure of resiliency or buoyancy to givea reasonable degree of comfort to the user, and the new pillowincorporating the present invention has such characteristic in adequateamount, due to the elasticity of the filling and to the fact that thethree strata of the cover allow air to escape therethrough thuspermitting compression of the filling under weight imposed thereon andadmit air to pass inwardly therethrough to permit ready expansion of thefilling when freed from its load resting thereon.

Such air expelled from and drawn into the pillow passes through thecotton-batting layer and its sized surfaces, but any feather, down orcomparable dust, powder or pith in the pillow cannot pass through theinner sized surface of the cotton-batting stratum which acts as afilter, thus preventing such possibly allergenic feather or downmaterial from coming into contact with the occupant of the pillow.

Experience has demonstrated that such surface of the batting remainsunbroken over a long period of service, even though the pillow isfrequently deformed more or less while in use.

If, in time, such inner sized surface becomes injured or deteriorated insuch a manner as to allow the specified dust to pass through it, thecotton of the layer and its outer sized surface then function as thefiltering media and the pillow continues thereafter for a long time togive effective and efficient service.

In this connection it is to be noted that the intermediate filteringmeans is attached to the inner and outer more or less poroustextile-fabric their two outer sheets H, H in direct contact casingsonly around the border of such means,

thus leaving the sized surfaces of the cottonbatting to vary in shape asoccasion requires and without substantial danger of rupture or breaking.

Inasmuch as none but the marginal parts of the cotton-batting arestitched and these are inside of the outer casing, there is no danger ofthe feather or down dust or powder passing outwardly through the smallopenings through which the thread of the stitching extends into theouter air and the entire surface of the filter unattached inwardly ofits border functions efficiently to perform its useful work.

In view of the fact that the cotton-batting is itself resilient, asomewhat lesser amount of feathers or of the relatively-expensive downmay be used as a filler without material or objectionable decrease inthe elasticity of the pillow as a whole.

Another distinct advantage resulting from the employment of the presentinvention resides in the reality that, due to the softness or insulatingquality of the glazedwadding, the pillows may be filled with cheapergrades of feathers than would otherwise be used and without theconsequent objection of feeling the quills or harshness prevalen't insuch lower type of feathers; in other words, the cotton-batting acts asan insulator, and, although the pillows may be filled with a lessexpensive grade of feathers, on their exteriors they will have a nice,soft, smooth feel or touch.

Those acquainted with this art will readily understand that theinvention is not necessarily limited and restricted to the precise andexact details of construction presented, since these may be modifiedwithin reasonable limits without departure from the heart and essence ofthe invention as defined by the appended claims and without the loss orsacrifice of any of the material advantages and benefits accruing fromthe employment of the invention.

I claim:

1. In an article, adapted to be used by a person occupying a bed or thelike, having an outer closed porous cover, an inner closed porous casinginside of said cover, an elastic filler-body of feathers, down or thelike, inside of said casing, and means securing said casing and covertogether around their entire margins, the novel features of afilter-envelope of cotton-batting between said cover and casing andenclosing said filler-body, said cotton-batting being sized throughoutat least one surface to render the article non-allergenic to personsallergic to said filler-body, the full length of the margin of saidsized cotton-batting filter-envelope being secured around the margin ofat least said casing or cover.

2. The novel features in the article set forth in claim 1 and whereinsaid filter-envelope is otherwise free from attachment.

3. The novel features in the article set forth in claim 1 in which saidcotton-batting filterenvelope is sized throughout both of its surfaces.

4. The novel features in the article set forth in claim 1 in which thearticle is of general rectangular shape and in which said cover, casingand filter-envelope each consists of top and bottom parts with threesections of the margin of each of said parts inturned and all securedtogether inside of said cover, the remaining marginal sections of saidparts being inturned and secured together at the exterior of saidarticle.
